摘要： A color cathode ray tube is composed of a glass bulb which has a front panel and a fluorescent screen set on an inner surface of the front panel, an in-line electron gun which is provided in the glass bulb and projects electron beams onto the fluorescent screen, a deflection means including horizontal and vertical deflection coils arranged outside the glass bulb, and a correction device for correcting cross-misconvergence. The correction device is provided with four correction coils that are respectively set for the four quadrants of a rectangular deflection region of the electron beams. The strength of the corrective magnetic fields generated by the correction coils becomes largest when the electron beams are deflected to a horizontal strip in the central part of both the upper and lower halves of the deflection region, and becomes nearly 0 when the electron beams are deflected to areas around the horizontal axis and top and bottom edges of the deflection region.

摘要： A pair of coma coils for correcting a VCR that is a positional displacement in a vertical axis direction of a center electron beam with respect to the center of a pair of side electron beams on a vertical axis in upper and lower portions on a screen are provided at a position in the vicinity of an end of a deflection yoke on an electron gun side. Assuming that a maximum value of the intensity of a vertical deflection magnetic field on a tube axis is HMAX, and the intensity of a vertical deflection magnetic field on the tube axis at the position where the pair of coma coils are arranged in the tube axis direction is HC, HC/HMAX≧0.8 is satisfied. Owing to this, high-order distortion of horizontal lines on a screen can be corrected.

摘要： On an outer circumferential surface of a neck portion of a funnel, a CPU having a pair of quadrupole magnets and a pair of bar-shaped magnets each having magnetic poles on both sides in a major axis direction are provided. The pair of bar-shaped magnets sandwich the neck portion substantially in an in-line direction of an in-line type electron gun, and are provided so that identical poles are opposed to each other, between an end plate of an insulating frame of a deflection yoke and the CPU at a distance from the end plate. In the case where a rotational shift of electron beams is caused, electron beams R and B are corrected so as to move upward and downward (or downward and upward) respectively by a quadrupole magnetic field generated by the quadrupole magnets. Then, the electron beams R and B are corrected so as to move downward and upward (or upward and downward) respectively by the quadrupole magnetic field generated by the pair of bar-shaped magnets. Thus, a misconvergence due to the rotational shift of the electron beams can be corrected.

摘要： When a deflection yoke is provided by winding horizontal deflection coils so that right and left ends of its bend portion on a screen face side protrude farther toward the screen face side than the center of the bend portion does, works for attaching vertical deflection coils and a core to an insulating frame can be carried out stably. The insulating frame is resin-molded so that an opening on the screen face side is shaped along the bend portion on the screen face side of a pair of upper and lower horizontal deflection coils. Protrusions (convexes) are provided at four positions between right/left portion “A” in a X-axis (horizontal axis) direction and top/bottom portion “B” in a Y-axis (vertical axis) direction of a periphery of the opening on the screen face side of the insulating frame.

摘要： A pair of velocity modulation coils are placed with a horizontal plane including a tube axis interposed therebetween, and a pair of magnetic substances are placed with a vertical plane including a tube axis interposed therebetween. A straight line portion of the velocity modulation coil extending substantially in parallel to the tube axis is placed between the magnetic substance and the tube axis. An interval D between the magnetic substance and the straight line portion is 1 to 3 mm. Assuming that the tube axis is a Z-axis, a size of the velocity modulation coil in a tube axis direction is L, and a position of an end of the velocity modulation coil on a side opposite to a phosphor screen in the tube axis direction is Z=0, a center point of the pair of magnetic substances in the tube axis direction is present in a range of Z=0.2×L to 0.9×L. Consequently, the sensitivity of velocity modulation can be enhanced while suppressing an increase in a driving power with a simple configuration.

To accomplish these objects, in a correction unit 340 provided with the deflection yoke 30 of the CRT apparatus 1 according to the present invention, a magnetic substance 342 having an attribute in which its permeability changes with a negative temperature characteristic is attached to a permanent magnet 341 so as to cover at least one of both end faces 341a and 341b. Additionally, in the deflection yoke 30, a paired correction units 340 is symmetrically placed at the top and the bottom of the deflection yoke, opposite to each other in respect to the tube axis of the CRT 10.

摘要： A deflection yoke device includes a deflection yoke for deflecting electron beams in horizontal and vertical directions, the electron beams being emitted from an electron gun of a color cathode ray tube; coma correcting coils positioned on an electron gun side of the deflection yoke so as to be opposed to each other in such a manner that the electron beams pass therebetween; and a pair of cores around which the coma correcting coils are wound, wherein a sliding mechanism is further provided for allowing each of the coma correcting coils to be slidable with respect to the corresponding core. Therefore, a misconvergence can be corrected by a simplified configuration without reducing a sensitivity of the coma correcting coils.
